Intersections using LED displays use approximately what percentage of power compared to incandescent displays?

LED displays are known for their energy efficiency, particularly when compared to incandescent bulbs. The percentage indicated in the question reflects the significant reduction in power consumption that comes with using LED technology. In comparison to incandescent displays, which are less efficient and consume more electricity to produce the same level of brightness, LED displays can operate at a fraction of that power requirement.

Specifically, LEDs typically use about 10% of the power that traditional incandescent bulbs consume to achieve a similar light output. This highlights the advantages of LED technology, not only in terms of energy savings but also in terms of longevity and reduced maintenance needs due to the longer lifespan of LED units. The choice of 10% correctly captures the efficiency of LED displays in traffic signal applications relative to their incandescent counterparts.
